前日有北大学生发帖称,一些社会人士进入校园,欲向未名湖放生约500只巴西龟,幸被制止。北京晨报记者昨日从北大保卫部证实了此事,工作人员称发现情况后立即对几位放生人士进行劝阻和教育,之后几人将这些巴西龟载离。据悉,近年来巴西龟颇受放生团体青睐,但专家提示,此类龟对本地龟造成物种侵害,影响区域水生态平衡,放生危害大。

回顾

校外人士放生受阻

前日,北京大学学生在校园论坛爆料有社会人士到北大放生巴西龟,“从车上搬下来好多袋巴西龟,初步估计有500只”。有学生看着不对劲上前提问,几人闭口不答,径直走向未名湖,其中两女子快速打开其中两个袋子准备放生,所幸被学生及时围堵,“问他们干嘛来,说是去年就来此放生,今年继续,只为修行。”

昨日上午,北京晨报记者从北京大学保卫部了解到,确有此事发生,不过这几人未成功放生,被巡逻保安和学生及时制止。工作人员对其询问后得知几人都是校外人士,“我们劝阻说,这些龟是入侵物种,对水域生物破坏很大,并让他们把这些巴西龟装车,驶离校园”。保卫部工作人员表示,考虑到不科学的放生会影响区域生态平衡,北大校园禁止放生行为。

巴西龟好养受青睐

冬季放生南方鸟类、林间放生毒蛇、污水区域放生鱼类,近年来,不少民间团体自发组织不当放生行为的事件不时见诸报端,其中巴西龟最受放生人士的欢迎。

在新官园花鸟市场,有店家向记者极力推荐放生巴西龟。“龟有灵性,这种巴西龟特别容易活,有水就行。”店家表示,相比其他龟类,巴西龟因为好养很受欢迎,常有人一次买几百只放生。记者走访几家店铺发现,从瓶盖大小到两个巴掌大的巴西龟都有售,价格从10元至300元不等。店家表示,如用于放生可以“便宜点儿”,“要多少有多少。”

但也有店家明确建议购买本土金线龟放生,“因为巴西龟便宜,很多人不懂,就买那个放生。但那个龟是外来物种,对本土的生物不好”。

■专家建议

巴西龟是著名生态杀手

北京师范大学生命科学学院牛翠娟教授说,巴西龟是著名的“入侵生物”,对入侵地区的生物多样性和生态系统会造成严重影响。“它会抢夺其他龟鳖类的食物和生存资源,挤压它们的生存空间,长期下来对本土龟鳖的生存影响十分严重。”由于巴西龟离开原有的生存环境后缺少天敌,适应能力和繁殖能力又远强于本土龟鳖,长久发展可能会导致部分本土龟鳖的消亡,“在一些盛行放生的水域,本土龟鳖生存环境十分恶劣。在一定程度上,放生巴西龟等同于谋杀本土龟类”。

同时,牛教授提示称,要在对本地环境和生物有充足了解的情况下再进行适量的科学放生。“你得保证放生动物能生存,同时也要保证它不会对其他物种造成入侵或伤害。”
